Communications Chip

Agere Systems Unveils Chip That Can Nearly Double Channel Capacity Of Computer Telephony Servers, Wireless Base Stations. Agere Systems, unveiled worldwide availability of a communications chip that nearly doubles the channel capacity of its nearest competitor for products such as computer telephony servers, voice over Internet Protocol gateways, and wireless base station controllers. A computer telephony server, for example, can now process nearly two times the number of phone calls using the Agere chip.

The chip for backplane interfacing and time slot switching offers easy bridging flexibility in switching voice and data signals, known as packet payloads. The payloads are switched between a local Peripheral Component Interconnect (PCI)* input/output bus and the widely used Enterprise Computer Telephony Forum (ECTF) H.100/H.110** data transport telephony bus. This bridging function allows for more flexible and efficient re-routing of traffic within the network, reducing congestion and connection costs.

The chip performs its functions by switching voice traffic and time division multiplexing (TDM) data between different network telephony line cards within communications equipment. Its primary function is to switch voice and TDM traffic to and from various devices and circuit boards within a voice/data processing system.

A member of Agere Systems' Ambassador( family of products, the T8110 PCI-Based H.100/H.110 Switch and Packet Payload Engine enables programmable switching of up to 4,096 voice channels-nearly twice as many as the nearest competing chip. This improved processing capability within the same amount of space reduces system integration, silicon, and circuit board costs for customers who use Agere Systems' new T8110 chip.

The chip has the capability to function as a bridge between the PCI bus and the H.100/H.110 telephony bus. It can also be used to control non-PCI devices, which are deployed within communications equipment, through a mini-bridge, further reducing system integration costs by eliminating the need for a separate microprocessor on the same board.

The T8110 can make programmable switching connections to any of the 4,096 time slots on the H.110 bus to manage time division multiplexing (TDM) traffic. Also, its function as a packet payload engine means the chip supports up to 512 virtual channels. This device is believed to be the industry's first to integrate packet handling with TDM voice traffic for computer telephony applications.

The T8110 can also simultaneously support multiple communications protocols, including Internet Protocol and Asynchronous Transfer Mode. To reduce system integration costs, support for non-PCI chips is provided through a mini-bridge.

The T8110 is Agere Systems' fifth in the Ambassador family of products, which provide switching access to the H.100/H.110 telephony bus.

This new product offers flexibility with its common pool of connection and data memory and its switching capability between the widely deployed PCI bus and the H.100/H.110 telephony bus. The T8110 chip can make many more connections than Agere's previous chips, yet these connections can be distributed among local to local streams, local to H.110 streams, local to PCI, H.110 to PCI, or any combination of these connection types. This capability takes the Ambassador product family to an even higher level of performance.

The chip is made within a 272 plastic ball grid array and uses a
0.2 micron process technology using a single 3.3 volts supply with 5 volt tolerant inputs and transistor-to-transistor compatible outputs. The chip is available using 0. 2-micron process technology and uses 3.3 volts with 5 volt tolerant inputs.
